The playboy founder of Manhattan’s Dream hotels, who once dated Gisele Bundchen and Kate Moss, is nursing yet another broken heart — from his supermodel ex-fiancée who absconded to Mexico with her $300,000 engagement ring.

Sad-sack eccentric hotelier Vikram Chatwal is now suing his famous DKNY-model ex, Esther Cañadas, in Manhattan Supreme Court to try to get back the 8-carat emerald and diamond token of his affection.

“The plaintiff, Vikram Chatwal, believed his dream had come true when defendant, Esther Cañadas, accepted his marriage proposal, but his dream morphed into a nightmare when upon the termination of the engagement, the defendant left the United States with the engagement ring as the spoils of the romance,’’ the suit says.

“The relief sought is the return of the engagement ring from the Defendant or a money judgment of $313,560, plus interest, costs, disbursements and reasonable legal fees, along with such other and further relief as this court may deem just and proper,’’ according to the papers.

The tumultuous pair were engaged in September, after the high-flying, hard-partying multimillionaire, 42, proposed to the pouty-lipped Cañadas, 37, during a visit to St. Patrick’s Cathedral in Midtown.

But Cañadas and Chatwal — who has also been linked to Lindsay Lohan — appeared troubled from the start. Just a few weeks later, the on-again, off-again couple said they were kaput for good.

Cañadas, who was born in Spain, now lives in the tony resort of Puerto Vallarta, Mexico. She could not reached for comment.

On his Vikram Chatwal Hotels Web site, he calls himself “an international tastemaker and man-about-town,’’ adding, “in 2005 he was named as one of the world’s most eligible bachelors by Radar Magazine.

“He is also well-known for his career as a Bollywood actor and friendships with some of Hollywood’s most influential stars,’’ says the site.

Chatwal still has a “G’’ tattoo on his left shoulder from his brief affair with Bundchen and parties on his 150-foot yacht “Fathom.’’

In 2011, he entered rehab for booze addiction.

He was then arrested at a Florida airport in April for drugs after he tried to board a plane with a stash of cocaine, pot and prescription pills — as well as heroin hidden in the crotch of his pants.
